On the last Saturday the 22nd of November, I attended BSidesVienna 2014 to deliver a talk about BurpSentinel. This tool is a Burp Suite extension giving better control over semi-automated requests sent to a given web application page. The presentation also covered aspects on automated Cross-Site Scripting and SQL injection detection. Despite talking early in the day (10 am), […]
Nowadays, we all relentlessly use search engines and developers extensively use version and source code control systems to keep track of their source code. Services such as Google or GitHub are great to search and retrieve information they gathered and stored. But when it comes to public indexing services, one big problem raises up: your whole […]
Compass Security employees identify and report on a regular basis security vulnerabilities as part of their daily assessments (or just out curiosity). Stefan Horlacher identified and reported back in June 2013 several flaws in SAP BusinessObjects Explorer. We’re happy to publish today the details as the flaws have been patched and a reasonable grace period […]
Back in Black (back from Black Hat with a bag full of schwag and branded black shirts). Black Hat and DEF CON again allowed insights into latest research and concerns. Where some topics loose grip ( vulnerability scanning, IPv4, DNS, general web issues) others gain momentum (DDoS, mobile computing, smart energy, industrial control and embedded […]
Cyrill Brunschwiler’s talk was selected “among the very best research available today” to be presented side-by-side with the security industries top researchers on the world’s most renowned security conference – Black Hat USA in Las Vegas. He will be speaking on “Energy Fraud and Orchestrated Blackouts: Issues with Wireless Metering Protocols (wM-Bus)”. The work presented […]
Cross-Site Scripting (XSS) has lost one rank in the newly released OWASP Top Ten 2013 candidate. Compared to the 2010 version, it’s now on rank three, overtaken by “Broken Authentication and Session Management”. Has XSS become less common then? No, I don’t think so. Compass Security has always been strong in web application security testing […]
As penetration testers, our main goal is to identify as many vulnerabilities as possible. This allows our customers to more objectifly assess their security level and to shut as many doors as possible which an intruder could use to break in. This process needs to be based in respect of cost-benefit, depending on risk probabily […]
Group Policy preferences are a new feature set available since Windows Server 2008, which shouldn’t be confused with the well known Group Policy objects (GPOs) dating back to Windows NT. The main idea behind the creation of Group Policy preferences is the ability to push so-called “unmanaged” settings. Compared to “managed” GPOs, group policy preferences can be altered by […]
Fridays, I was approaching a win32 reversing challenge. So I transferred the binary into my Windows XP virtual box and fired-up OllyDbg. The goal was to bypass the username and password prompt that occurred on application startup. Hilariously, I was just providing a dummy name and password to the app…. “asdf” “asdf” as probably most […]
Developers increasingly integrate BeanShell support into web applications to provide end users and administrators with a simple extension framework. But be warned! BeanShell support without appropriate access control will put the hosting web server at severe risk. An attacker could easily execute operating system calls and without appropriate system hardening such an attack will immediately result in full system compromise. The […]
